thrust horsepower[′thrəst ′hȯrs‚pau̇·ər]
The force-velocity equivalent of the thrust developed by a jet or rocket engine.
The thrust of an engine-propeller combination expressed in horsepower; it differs from the shaft horsepower of the engine by the amount the propeller efficiency varies from 100%.
The product of the speed of advance of a marine propeller through the water, in feet per second, and the thrust delivered by the propeller, in pounds, divided by 550.
The amount of horsepower the engine-propeller combination transforms into thrust. The terms brake horsepower and shaft horsepower are more often used for reciprocating engines rather than thrust horsepower. In gas turbine engines, it is the force-velocity equivalent of the thrust developed by the engine.
